摘要：
Solid alkaline electrolyte membranes were prepared using poly(vinyl alcohol)/poly(vinyl pyrrolidone) (PVA/PVP) by KOH doping. The composition, microstructure, thermal stability, ionic conducitvity and methanol uptake of the composite membranes were investigated in detail. The wholly transparent, homogeneous and compact PVA/PVP/KOH composite membranes were obtained when m(PVA). m(PVP)= 1:0.5 in a mass ratio and no obvious phase seperation was observed. The ionic conductivity and thermal stability of the PVA/PVP membranes increased greatly with increasing the content of PVP. A high ionic conductivity of 2.01x10(-3) S.cm(-1) was obtained when a mass ratio of m(PVA). m(PVP)= 1:1 was used. In additon, the methanol uptake of the PVA/PVP/KOH membranes showed almost no change after conditioning at elevated temperatures and it was 4 times lower than that of the Nafion 115 membrane after conditioning at 100 degrees C. These membranes are, therefore, promising solid alkaline electrolyte membranes for use in alkaline direct methanol fuel cells at elevated operating temperature.
